MACHINE FOR MOLDING FENCE-POSTS.

SPECIFICATION forming part of Letters Patent No. 513,751, dated January30, 1894.

Application filedFebrnary 11, 1893. Serial No. 461,934. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM BAYLEY, a citizen of theUnited States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Fence-Post-MoldingMachines,

an enlarged scale of a portion of the same. Fig.3 is a sectionalelevation of Fig. 2. Fig.

4: is a transverse'elevation of the same. Fig. 5 is a detail referred tohereinafter. Fig. 6 is a plan View, showing diiferent stages of theoperation of molding and some modifications. Fig. 7 is a perspectiveview of a box or flask, which may be employed if desired in connectionwith the other mechanism. Fig. 8 is a sectional view of the mold andpattern therein. Fig. 9 is a similar view showing the pattern withdrawnand the mold ready for casting. Fig. 10 is a plan view of the copeadapted to form the top of the'mold. Fig. 11 is a perspective view indetail of a modification of the same. 7

Like parts are represented by similar letters of reference in theseveral views.

In the said drawings A A, represent a flask or pit in which the moldsare to be formed. It is preferably arranged in the nature of a pitarranged along the side or other convenient place of the foundry and isprovided at the top with a metallic frame A, having suit able cross barsa, at convenient points in the length thereof, the frame being providedwith suitable engaging hooks or bails o by means of which, and the aidof blocks and tackle or other suitable hoisting device, the frame may beraised from the top of the pit and the sand, from which the molds are tobe formed, removed and replaced as desired. The frame A, carries, inaddition to the cross bars a, a

series of vertical standards B, (see Fig. 5 for detail) which extendupwardly from one side of said frame and are curved outwardly andprovided at their upper extremities with an open recessed bearing b,adapted to be closed by a hinged latch b, pivoted at 19 so as to beturned back, as indicated in dotted lines in Fig. 5.

Arranged above the frame A, and parallel thereto, are suitablesupporting ways 0 c, which extend the full length of the flask or frameand vertically above the same. Located on said ways 0 c, and supportedthereon by means of supporting wheels 0 having grooved peripheries toengage said ways is a traveling frame D. This traveling frame isprovided wi thvertical guides or ways d; betweenwhich is located areciprocating head or hammer E,

the upper end of which is connected to a rope E, which passes over asuitable supporting sheave E at or near the top of the frame D, andthence downwardly in convenient reach of the operator. The lower ends ofthe ways 01, are connected by a cross bar (1, formed with a centralopening or hearing adapted to receive a rod or shaft F, which projectsupwardly through said opening and is connected at the top to a cross baror head F, preferably formed in two parts and adapted to engage and beguided by the ways (1. This rod or shaft F, carries at the bottom andbelow the cross bar d, the pattern G,Which corresponds in shape and sizeto the base of the completed fencepost. Means are provided by which thehead F, and the hammer E,

may be connected together or detached from each other, and an auxiliaryhoisting device E is preferably provided at one side of the frame 01,and adapted to engage with a hookshaped projection E on the hammer E, toraise the same when drawing the pattern in the manner hereinafter morefully specified.

This connection preferably consists in a bifurcated L-shaped connectingbar F adapted to embrace the rod F, and engage below the head F, and beconnected to the hammer E, by a removable pin F In operation thetraveling frame D, together with the pattern G and its supporting rod F,

normally connected with the hammer E, is

moved along the ways until it is brought 0pposite one of the standardsB. The latch 12,

is raised and the supporting rod F, of the pattern-is-placed within therecessed bearing 1), of said standard, after which the latch b isclosed, thus retaining and guiding the rod F, in the proper positionover the flask or pit containing the sand in which the mold is to beformed. The hammer and the pattern are now detached by withdrawing thepin F and removing the connection F The pattern is allowed to descendand enters into the sand in the flask or pit which has been previouslyprepared. The hammeris raised in the guides or ways by means of theelevating rope E, and is permitted to descend by gravity, striking thetop of the rod F, and driving the pattern into the sand to the properdistance, afterwhich'the hammerE, and pattern G, are connected together,as before described, the auxiliary hoisting device E connected to saidhammer and the parts elevated to their normal position, thus withdrawingthe pattern -from the sand andleaving'the imprint of the said patterntherein.

-Thetop of the mold is closed and the upper part thereof formed by acope. This cope may be'either formedby a chill, or may bema'deofdr'ysand, formed and bakedin a core box afterthenature of a core, inthe usual'manner. When the dry sand cope is employed, "an auxiliaryframe or pattern is placed at the top of themain'pattern prior towithdrawing thesame and a print formed to receive the 'cope,which isplaced at the top of the mold 's'oas' toform the upper part of the sameafter the pattern is-withdrawn. This cope ispreferably provided with anopening through; "which themolten metal is poured in casting itis alsoprovided with a central opening; adapted to receive the post proper,which is? to'be m'ade of other metal and cast into the base. This isp'referably'formed of tubular m'etahcommon Wrought ironpipe being'pref-gerably'used. Afterthe pattern iswithdrawni and'removedfrom thesupporting staudardB, thepostproper being first provided with'atietachable collar 6 arranged at a suitable distance from the bottomthereof, is inserted 'ftliroughthe top of the cope so as to projectintothe mold to the proper distance andthe upper end thereof supported inthe bearing inthe standard 13, as shown at the left of Fig. 1 when themold is ready to receive the metal in casting. V

\Vhen the chill is employed an auxiliary framef, is preferably providedat thetop of "the flask or pit resting on the sand immediately uponthepattern, this frame being adaptserted within the frame f, said chillbeing formed to fit snugly within said frame and provided with asuitable inlet opening g, for the metal, the detachable collar e, beingprovided for the inserted post e, as before described.

By the constructions above described it will be seen that the operationof forming a mold for a fence post is reduced to the simplest possiblecharacter. Any suitable number of molds may be formed, the supportingways and the pit orfiask being extended as desired, and by thearrangement of driving and removing the pattern, together with thesupporting ways and standards, the work is reduced to a simplemechanical operation, requirin g an ordinary mechanic and dispensingwith askilled laborer usually employed in molding and casting articlesof this character.

As before stated I preferably form the molds in the pit inthe floorofthefoundry,withthe movable frame A, adapted to form the top thereof.It is obvious, howeventhata flask, such as shown in Fig. 7 maybeemployed if desired and elevated above-the floor/the constructionbeing'in no-wise changed in this case.

Having thus described my invention, I claim I 1. In a molding machine, aremovable frame having a series of supportingstandardswith open bearingstherein, a'travelingframe arranged on ways being paralleltosaidframe, areciprocating hammer in said traveling "frame, a pattern also arrangedin saidtraveling frame, and'means forcon'nectingand detaching saidpatternfrom saidhammer, substantially as specified.
